Page numbers turn a stack of pages into a referenceable document. A judge quotes “page 14 of the exhibit”, a reviewer says “the footnote on page 8”, and a thesis examiner checks the bibliography against a page list. Numbering a PDF well looks trivial, but three choices decide whether it is useful: position, format and starting value.
Where the numbers should go
The bottom is the default for nearly every serious document. Bottom-center is standard for books and reports; bottom-right is common for court filings and contracts. Top positions are fine for simple internal documents, but readers flipping through expect the number at the bottom, where page numbers have lived since the printed era.
Choosing the format
- Plain numbers (3, 4, 5) — the default for anything paginated by position.
- "Page 3" — a slightly more formal look for reports and proposals.
- "Page 3 of 12" — the “of” format, invaluable when printed pages will be separated or a reader must know the document’s total length.
The “page X of Y” form earns its keep in exactly one scenario: when someone prints the PDF. A standalone printout instantly reveals whether it is page 3 of a 12-page brief or page 3 of a 200-page treatise — which is why courts and regulators favor it.
Starting from any number
Not every document starts at page 1. If you merge three chapters, chapter two might need to continue at page 35. If a cover page and a table of contents lead the document, you often want the first numbered page to be the first content page, not the cover. A start value lets you jump straight to the right number without editing anything.
One caveat about true Bates numbering: sequential legal numbering (often with prefixes like “ABC-000123”) is more than page numbers — it is an identifying scheme used during discovery. A plain page-numbering tool positions the digits; Bates-style prefixes with fixed-width zeros are usually better produced by dedicated litigation software.
Margins and overlap
Numbers are placed about a centimeter from the page edge, which clears normal margins. On pages with unusually tight margins — dense tables, footnotes pushed to the very edge — the number can collide with content. Glance at a few interior pages after stamping, not just the first one.
Because numbering writes a fresh copy locally in your browser, the process is private and the original file stays untouched. There is no upload, which makes the tool comfortable for documents that are not yet cleared for circulation.
